Abstract.The equations governing the quasi-one-dimensional steady flow of a conducting perfect gas in crossed, transverse electric and magnetic fields are treated under the assumptions that the electric conductivity is a scalar, that the wall drag is small and that the magnetic field due to the currents in the gas is negligible. The equations are normalized and different flow situations are illustrated by means of phase diagrams (drawn for a gas of constant specific heats, 7 = 1.33).
The viscous model of the solar wind formulated by Whang et al. is examined. The results are qualitatively and quantitatively different from those published earlier. The reasons for the quantitative discrepancies were found, so that by deliberately introducing certain specified errors we could accurately reproduce the earlier results. Qualitatively, a new two‐parameter family of asymptotic solutions is found, in addition to the one‐parameter family for which the earlier computations were made. The special computational difficulties inherent in the problem are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
